The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [7] [8] [9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member of the Laniakea Supercluster. CfA2 Great Wall (1989) 750,000,000: Also known as the Coma Wall. Saraswati Supercluster: 652,000,000 [22]

The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 ...
It is located in our Milky Way galaxy about 520 light-years from Earth. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
The planet is located in our Milky Way galaxy about 41 light-years from Earth, in the constellation Cancer. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
The Sun is part of one of the Milky Way's outer spiral arms, known as the Orion–Cygnus Arm or Local Spur. [270] [271] It is a member of the thin disk population of stars orbiting close to the galactic plane. [272] Its speed around the center of the Milky Way is about 220 km/s, so that it completes one revolution every 240 million years. [269]
The Milky Way galaxy is a member of an association named the Local Group, a relatively small group of galaxies that has a diameter of approximately one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group; many of the other member galaxies are dwarf companions of these two. [176]
